Allograft biopsy in kidney transplant recipients in the medical city of Baghdad

Abstract

To determine the safety and efficacy of the practice of renal allograft biopsy and verify its impact on the management of kidney transplant patients presenting with graft dysfunction, we studied 50 renal allograft biopsies of 47 adult patients (38% males, mean age 32.4 ± 11 years) performed in the medical city complex from November 2008 to April 2011. All the biopsies were performed with a guidance of ultrasound. The procedure, complications, histological diagnoses and impact of the biopsy data on patients' management were recorded. Thirty percent of the biopsies were performed in the first 12 months post-transplantation and 24% were performed after the 60 th month. Adequate biopsy was achieved in 76% of the patients, with a 96% safety rate. Acute rejection was diagnosed in 38% of the biopsies and chronic allograft nephropathy in 38%, and they were the most common histological patterns in the study. The results of allograft biopsies positively impacted the management strategy in all study groups. Renal allograft biopsy was a useful and a relatively safe tool for the diagnosis of acute and chronic graft dysfunction in our experience.
